Bluetooth device connection method and device

Abstract

A Bluetooth communication system, including first and second Bluetooth devices. The second device includes a second Bluetooth application and a second Bluetooth host. The first device sends advertising information that includes UUID information of a service supported by the first device; the second host receives the advertising information, the advertising information includes the UUID information of the service supported by the first device; the second host stores and parses the UUID information, and sends a pairing request to the first device; the first device pairs with the second device; the second device instructs the second host to report pairing to the second application, the pairing information including UUID information of the service supported by the first device; the second Bluetooth device sends a service connection request to the first device; and the first device is further configured to establish a service connection to the second device.

What is claimed is: 
     
       1. A Bluetooth device, comprising:
 a Bluetooth module, configured to communicate with another Bluetooth device, wherein the Bluetooth module comprises a Bluetooth host and a Bluetooth application; and 
 the Bluetooth module further comprises one or more processors; and 
 a memory, wherein the memory comprises instructions, and when the instructions are executed by the one or more processors, the Bluetooth device is enabled to perform the following operations: 
 searching for an available Bluetooth device; 
 receiving advertising information sent by the available Bluetooth device, wherein the available Bluetooth device comprises a first Bluetooth device, and advertising information of the first Bluetooth device comprises universal unique identifier (UUID information of a service supported by the first Bluetooth device; 
 storing and parsing the UUID information that is of the service supported by the first Bluetooth device and that is comprised in the advertising information of the first Bluetooth device; 
 instructing the Bluetooth host to pair with the first Bluetooth device; 
 instructing the Bluetooth host to report pairing information to the Bluetooth application, wherein the pairing information comprises the UUID information of the service supported by the first Bluetooth device; and 
 in response to pairing with the first Bluetooth device, establishing a service connection to the first Bluetooth device based on the UUID information of the service supported by the first Bluetooth device. 
 
     
     
       2. The Bluetooth device according to  claim 1 , wherein the advertising information is Bluetooth low energy advertising. 
     
     
       3. The Bluetooth device according to  claim 1 , wherein the advertising information is extended inquiry response information. 
     
     
       4. The Bluetooth device according to  claim 1 , wherein the UUID information of the service supported by the first Bluetooth device comprises UUID information of a voice hands-free profile (HFP) and an advanced audio distribution profile (A2DP). 
     
     
       5. A Bluetooth device, comprising:
 a Bluetooth module, configured to communicate with another Bluetooth device, wherein 
 the Bluetooth module further comprises one or more processors; and 
 a memory, comprising instructions, wherein when the instructions are executed by the one or more processors, the Bluetooth device is enabled to perform the following operations: 
 sending advertising information, wherein the advertising information comprises universal unique identifier (UUID) information of a service supported by the Bluetooth device; 
 receiving a pairing request of a first Bluetooth device; 
 pairing with the first Bluetooth device in response to the pairing request of the first Bluetooth device; 
 in response to pairing with the first Bluetooth device, receiving a service connection request of the first Bluetooth device, wherein the service connection request of the first Bluetooth device comprises a part or all of the UUID information of the service supported by the Bluetooth device; and 
 establishing a service connection to the first Bluetooth device in response to the service connection request of the first Bluetooth device. 
 
     
     
       6. The Bluetooth device according to  claim 5 , wherein the advertising information is Bluetooth low energy advertising. 
     
     
       7. Bluetooth device according to  claim 5 , wherein the advertising information is extended inquiry response information. 
     
     
       8. The Bluetooth device according to  claim 5 , wherein the UUID information of the service supported by the electronic device comprises UUID information of a voice hands-free profile (HFP) and an advanced audio distribution profile (A2DP). 
     
     
       9. A Bluetooth communication method applied to a Bluetooth device, wherein the Bluetooth device comprises a Bluetooth host and a Bluetooth application, and the method comprises:
 searching for an available Bluetooth device; 
 receiving advertising information sent by the available Bluetooth device, wherein the available Bluetooth device comprises a first Bluetooth device, and advertising information of the first Bluetooth device comprises universal unique identifier (UUID) information of a service supported by the first Bluetooth device; 
 storing and parsing the UUID information that is of the service supported by the first Bluetooth device and that is comprised in the advertising information of the first Bluetooth device; 
 instructing the Bluetooth host to pair with the first Bluetooth device; 
 instructing the Bluetooth host to report pairing information to the Bluetooth application, wherein the pairing information comprises the UUID information of the service supported by the first Bluetooth device; and 
 in response to pairing with the first Bluetooth device, establishing a service connection to the first Bluetooth device based on the UUID information of the service supported by the first Bluetooth device. 
 
     
     
       10. The method according to  claim 9 , wherein the advertising information is Bluetooth low energy advertising. 
     
     
       11. The method according to  claim 9 , wherein the advertising information is extended inquiry response information. 
     
     
       12. The method according to  claim 9 , wherein the UUID information of the service supported by the first Bluetooth device comprises UUID information of a voice hands-free profile (HFP) and an advanced audio distribution profile (A2DP).
